I provide more details to the intersection theoretic results in [1]. CONTENTS 1. Transversality and tubular neighborhoods 1 2. The Poincaré dual of a submanifold 4 3. Smooth cycles and their intersections 8 4. Applications 14 5. The Euler class of an oriented rank two real vector bundle 18 References 20 1. TRANSVERSALITY AND TUBULAR NEIGHBORHOODS We need to introduce a bit of microlocal terminology. We begin by reviewing a few facts of linear algebra. If V is a finite dimensional real vector…

It is well-known (see eg [22]) that the topology of a compact Kähler manifold X is strongly restricted by Hodge theory. In fact, Hodge theory provides two sets of data on the cohomology of a compact…

### INTERSECTION MULTIPLICITY ON BLOWUPS

- Mathematics

One way to reformulate the celebrated theorem of Beilinson is that (O(−n), . . . ,O) and (Ω(n), . . . ,Ω(1),O) are strong complete exceptional sequences in D(CohP), the bounded derived category of…

### Equivariant classes of matrix matroid varieties

- Mathematics

To each subset I of {1, . . . , k} associate an integer r(I). Denote by X the collection of those n × k matrices for which the rank of a union of columns corresponding to a subset I is r(I), for all…

### Degeneracy Loci in Cr Geometry .1 Introduction

The geometry of complex subspaces contained within real subspaces of a complex vector space is described in detail in Section 2. This leads to an analysis of real subbundles of a complex vector…

### Diagonal Subschemes and Vector Bundles

- Mathematics
- 2006

We study when a smooth variety X, embedded diagonally in its Cartesian square, is the zero scheme of a section of a vector bundle of rank dim(X) on X × X. We call this the diagonal property (D). It…
